RENESAS HIP4082IBZ Full Bridge MOSFET Driver IC, SOIC-16, 1.4A

The RENESAS HIP4082IBZ is a medium-frequency, medium-voltage half-bridge N-channel MOSFET driver integrated circuit. It is specifically targeted for PWM motor control and UPS applications, simplifying and adding flexibility to bridge-based designs. With an operational capability up to 80V, the device is ideally suited for applications with moderate power levels, offering a robust solution for demanding electronic environments.

The driver features a flexible input protocol capable of driving every possible switch combination, intelligently excluding those that could cause a damaging shoot-through condition. Its reduced drive current requirements allow for smaller component packaging, while a wide range of user-programmable dead times from 0.1 to 4.5ms makes it perfect for switching frequencies of up to 200kHz.

Key Features & Design

The HIP4082IBZ does not contain an internal charge pump but incorporates non-latching level-shift translation control for the upper drive circuits. This design efficiently and independently drives four N-channel FETs in a full-bridge configuration. It offers comprehensive protection features, including shoot-through prevention and under-voltage lockout to safeguard your circuitry.
